Here are a few common questions answered by the Experts on JustAnswer about air dampers.
Why is a side by side Frigidaire refrigerator freezing the contents irrespective of the thermostat setting?
This refrigerator will have an air damper located at the left rear upper corner. You will need to test the control using an OHM meter as well as the damper motor. Before checking the refrigerator, it should be unplugged for your safety. The refrigerator control panel usually has two terminals. When the control signals the damper to open, the contact is closed leading to continuity across the terminals.
If you have two terminals on the control panel, you can bypass across the two wires and re-plug the refrigerator instead. The damper should close when you do this. If it does not, check to see if 120 volts are going to the damper motor. Professional technicians recommend changing the entire assembly if you face problems with several components of an air damper.

If an air damper between the freezer and a fridge on a Kenmore refrigerator is not opening and the air damper has been replaced, but no change what could be the problem?
The air damper control lies with the main board. However, the problem could lie with the temperature sensor or the main control board. In most cases, it does not make much difference whether the damper closes or not.
You can opt for a temporary solution by using an object to wedge into the damper leaving it half open. Check the functioning of the fridge after this too see if everything is okay. If this has not helped, you should probably replace the sensor and board.
What is a damper assembly?
